Hello everybody, been a very long time since I posted last.
Anyway, recently bought a pod HD500. It's great, having a blast with it except the '4' dial under the lcd screen is very unresponsive. If I turn it, there's no way possible for me to change the value to what I want. It will jump from 0 to 200 and back, or any number infact.

Now I believe it's just a dodgy pot? And that cleaning it could fix the issue? I've been out of the game for too long so if this isn't the solution im after I'd massively appreciate any help.

Thanks guys.
First try reinstalling the firmware. Grab a fresh version from Line 6.
